CAN-OPENER.

new and useful Im rovements in Can-Openers, of which the fo owing is a full, clear, and exact description.

The invention relates t0 can-openers and designs to provide an improved device which, when operated, will cause relative movement of the can and cutter to facilitate the opening operation and to make it unnecessary to manually manipulate the cutter to advance it over the can.

The invention further designs to provide a can-opener of improved construction and which may be conveniently operated without danger of injury to the hands ofthe operator.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claim at the conclusion hereof.

In the drawings: Figure 1 is an elevation of a device embodying the invention. Fig. 2 is a section on line 2-2 of Fig. 1, on a larger scale. Fig. 3 is a section taken on line 3-3 of Fig. 2 and Fig. 4 is a horizontal section on line 4-4 of Fig. 2, illustrating the device in operation. Fig. 5 is an elevation viewed from the outer siile, of the parts illustrated in Fig. 3.

A supporting frame 10 of any suitable form is provided which may be secured in any convenient position, e. g., to a Wall or table, by bolts 11. A can-support 12 is secured to a lprojecting arm 13 of the frame 10 a nd is usually of such size as to support the largest can to be opened. Lugs 14 are provided to guide the lower portion of the can against lateral movement duringthe operation of the opener. The supporting-frame 10 is provided with a bracket 15 having a -vertical guide or channel 16 formed therein. A cutter supporting-bar 18 is held in channel 16 of bracket 15, by a cap 17 so it may be raised or lowered to bring the cutter into operative position or relation with respect to the tops of cans of different lengths. A setscrew. 19 serves to secure the bar 18 in assigned osition when desired. y

The ower terminal of bar 18 is beveled or ointed as' at 20 to form means for puncturing the can and which may be forced through the top thereof. Ashort distance above the lower terminal of the bar it is cut away to Specification of Letters Patent. Application mea November 4, 1007. serial No. 400,574.

form a knife or cutter 21 which has an edg adapted to cut the metal of the can when relative movement is imparted to the cutter .and can. Bar 18 is usually formed of suitable material, such as tool-steel, so-that the cutter may be formed by an integral part thereof.

A pair of feed-rolls or wheels are j ourna'led in bar 18. Said rolls are adapted to grasp the top of the can and feed it to the knife. The upper of these feed-rolls 24 is disposed in a recess formed in the cutter-support or bar eration to engage the outer surface of the in a recess 26 formed near the lower end of bar 18, being revolubly mounted on a stud 27. The eripheries of the feed rolls are disposed wit respect to the cutter, so that the metal of the top or-Wall of the can to be opened will be Within the bite of the feedrolls7 each of which is referably provided with teeth to firmly hol and feed the material. These feed-rolls are disposed so that they will bite into the wall of the can to be cut, in advance of the knife, so that the feedrolls will take hold of an unsevered portion of the wall of the can The upper feed-roll 24 is journaled on the reduced portion 2,9 of a stud 30 of a crank 31, which is journaled in the cutter-sup ort or bar 18, the crank bein secured to said stud 30 or integrally forme therewith. The reduced portion 29 of the stud is suitabl connected to the feed-roll 24 so that it will rotate with the crank. A washer 33 and screw 34 connect the crank and feed-roll 24 against lateral movement in supporting-bar 18, the crank forming a shoulder for one side of the support and the roll fitting against the other side so that the journal-portion 30 will be free to revolve in the sup ort. l

e operation of the device will be as follows: The can to be o ened is placed on the support 12, the outer ug 14 being disposed so that the edge of the can will be properly positioned to cause the cutter to penetrate the top near the edge of the can. Bar '18 will then be lowered or driven to cause the terit to bring t e top of the can substantially in the lace of the cutter 21 and between the fee rolls. The can will then be turned slightly to bring the edge around the punctured ortion into the bite of and between the ro ers. The support 18 may be held in 18 and is disposed above the can when in opcan-top. A small feed-wheel 25 is disposed minal 20 to uncture the can and penetrate cutter, feed-rolls for effecting relative moveinner and outer surfaces respectively of that proper elevation to cause the cutter to' remam in the plane at the top of the can b screw 19. By turning the crank 31 the fee rolls will be operated' to feed the can to the knife until the entire to or so much thereof as may be desired, has been cut.

Manifestly,.the invention provides a canopener of simple construction which may be convenientl operated without'danger of injury to the lliands and in which feed-rolls are; provided for 'effecting the relative movement of the cutter and the can during operation.

The invention is not to be understood as. restricted to the details set forth since these may be modified within the scope of the a pended claims without departing from t e spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire/to secure by Letters Patent, is: a,
